BACKGROUND 1. Field

Embodiments of the present invention relate to a receiving device inwhich a detector is accommodated and an X-ray imaging apparatus havingthe same.

2. Description of the Related Art

An X-ray imaging apparatus is a non-invasive diagnostic apparatus thatradiates X-rays to a subject, detects X-rays transmitted through thesubject, and can image an internal structure of the subject.

Since general X-ray imaging apparatuses have an X-ray source and anX-ray detector, which are fixed in a certain space, a patient moves to alaboratory in which the X-ray imaging apparatus is positioned and moveshis or her body to adjust to the apparatus in order to perform X-rayimaging.

However, since movement-impaired patients have difficulty in imagingusing general X-ray imaging apparatuses, a mobile X-ray imagingapparatus capable of performing X-ray imaging at any place wasdeveloped.

The mobile X-ray imaging apparatus can perform X-ray imaging by directlyvisiting movement-impaired patients since an X-ray source is mounted ina movable main body and a portable X-ray detector is used.

The mobile X-ray imaging apparatus includes a receiving unit, and theportable X-ray detector may be accommodated in the receiving unit. Forconvenience of X-ray imaging, portable X-ray detectors of various sizeshave been recently provided.

When a portable X-ray detector of a small size is accommodated in areceiving container that is provided according to a size of a portableX-ray detector of a large size, the portable X-ray detector may move inthe receiving container when the mobile X-ray imaging apparatus ismoved. Therefore, the portable X-ray detector comes in contact with aninner sidewall of the receiving container so that noise may be generatedor the portable X-ray detector may be damaged.

In order to prevent the portable X-ray detector from being unstablyaccommodated in the receiving unit, the receiving unit of the mobileX-ray imaging apparatus may include the receiving container in whichreceiving units according to sizes of portable X-ray detectors havingvarious sizes are provided to accommodate portable X-ray detectors ofvarious sizes. In this case, since a size of the receiving unit in whichthe portable X-ray detector is accommodated increases, space utilizationis limited.

The otherside of the detector support 23 may support one surface of the detectingdevice 3 such that the detecting device 3 can be stably accommodated inthe receiving unit 11.

In this manner, when the detecting device 3 having a horizontallyextending length L that corresponds to a length L1 from the one surface121 a of the first insertion groove 120 a to the one surface 121 b ofthe second insertion groove 120 b of the side fixer 12 provided in thereceiving device 10 is inserted into the receiving unit 11, the detectorsupport 23 may be rotated by the detecting device 3 not to interferewith movement of the detecting device 3.

The detecting device 3 may be accommodated in the receiving unit 11 whena front surface comes in contact with the detector support 23, a rearsurface comes in contact with the support 14, and parts of both sidesurfaces are inserted into the first insertion groove 120 a and thesecond insertion groove 120 b.

The receiving unit 11 of the receiving device 10 may be formed at aslant to have a predetermined angle. In other words, the receiving unit11 of the receiving device 10 may be formed to be inclined to have apredetermined angle with respect to a virtual line G extending in thedirection of gravity. Preferably, the receiving unit 11 of the receivingdevice 10 may be formed to be inclined to have an angle greater than 0°and equal to or less than 90° with respect to the virtual line Gextending in the direction of gravity. More preferably, the receivingunit 11 of the receiving device 10 may be formed to be inclined to havean angle greater than 0° and equal to or less than 45° with respect tothe virtual line G extending in the direction of gravity. As an example,FIG. 8 illustrates the receiving unit 11 of the receiving device 10formed to be inclined to have an angle of about 26° with respect to thevirtual line G extending in the direction of gravity. When the receivingunit 11 of the receiving device 10 is formed in parallel to the virtualline G extending in the direction of gravity, because the size ofgravity acting on the detecting device 3 is relatively large, arelatively large impact may be applied to the detecting device 3 whenthe detecting device 3 is accommodated in the receiving unit 11 of thereceiving device 10. Conversely, when the receiving unit 11 of thereceiving device 10 is formed to be inclined to have an angle of 90°with respect to the virtual line G extending in the direction ofgravity, because the size of gravity acting on the detecting device 3 isrelatively small, a relatively small impact may be applied to thedetecting device 3 when the detecting device 3 is accommodated in thereceiving unit 11 of the receiving device 10. However, when thereceiving unit 11 of the receiving device 10 is formed to be inclined tohave an angle of 90° with respect to the virtual line G extending in thedirection of gravity, a user has to accept inconvenience of having tobend his or her waist and the like to store the detecting device 3 inthe receiving unit 11 of the receiving device 10. Consequently, it ispreferable that the receiving unit 11 of the receiving device 10 beformed to be inclined to have an angle greater than 0° and less than 90°with respect to the virtual line G extending in the direction ofgravity. However, because an amount of impact applied to the detectingdevice 3 may be defined by various parameters such as a weight of thedetecting device 3 and a frictional coefficient of the detecting device3, the extent to which the receiving unit 11 of the receiving device 10is inclined is not limited to the above example. For reference, an angleof the receiving unit 11 of the receiving device 10 is measured withrespect to a surface of the detecting device 3 accommodated in thereceiving unit 11 of the receiving device 10. As an example, in the caseof FIG. 8, the angle of the receiving unit 11 of the receiving device 10is measured with respect to a surface of the detecting device 3 facingthe inner rear surface 111.

Hereinafter, a case in which the detecting device 3 whose horizontallyextending length is L that is the same as a length L2 from the onesurface 121 a of the first insertion groove 120 a to the first sideportion 21 of the guide 20 is stably accommodated in the receiving unit11 of the receiving device 10 will be described.

FIG. 9 is a side view of a guide when a guide according to an embodimentof the present invention is in a second position. FIG. 10 is a side viewof a receiving device when a guide according to an embodiment of thepresent invention is in a second position.

As illustrated in FIGS. 9 and 10, a horizontally extending length L ofthe detecting device 3 according to the embodiment of the presentinvention may be any of a length L2 from the one surface 121 a of thefirst insertion groove 120 a of the side fixer 12 to the first sideportion 21 of the guide 20 and a length L3 from the one surface 121 b ofthe second insertion groove 120 b of the side fixer 12 to the secondside portion 22 of the guide 20. Hereinafter, the horizontally extendinglength L of the detecting device 3 will be described as the length L2from the one surface 121 a of the first insertion groove 120 a of theside fixer 12 to the first side portion 21 of the guide 20.

Meanwhile, when the detecting device 3 whose horizontally extendinglength L corresponds to the length L1 from the one surface 121 a of thefirst insertion groove 120 a to the one surface 121 b of the secondinsertion groove 120 b of the side fixer 12 provided in the receivingdevice 10 is removed from the receiving unit 11, a force pressing thedetector support 23 is removed, and the other side of the detectorsupport 23 may be rotated to face behind the accommodating member 10 dueto the elastic force of the elastic member 24. That is, the detectorsupport 23 may rotate in a direction t3 that is a direction opposite tothe direction t1 with respect to the rotating shaft 26.

The detector support 23 has a rotating angle that may be restricted bythe intervention unit 211 inserted into the rotation restricting portion231. The detector support 23 may be rotated at a maximum rotating angleby the rotation restricting portion 231 and the intervention unit 211and then stopped. Meanwhile, the detector support 23 may be rotateduntil the other side thereof comes in contact with an inner rear surfaceof the receiving device 10 forming the receiving unit 11.

When the detector support 23 is rotated in the direction t3, the elasticmember 24 positioned between the detector support 23 and the supportbracket 25 can expand. At least a part of the elastic force stored inthe contracted elastic member 24 is used to rotate the detector support23. When the detector support 23 is rotated at a predetermined angle,the elastic member 24 may expand and have an elastic force smaller thanthat before the detector support 23 is rotated.

When the detecting device 3 whose horizontally extending length is L1 isremoved from the receiving unit 11, a first section (length: L1) fromthe one surface 121 a of the first insertion groove 120 a of the sidefixer 12 to one surface of the second insertion groove 120 b may bepartitioned by the detector support 23 into a second section (length:L2) from the one surface 121 a of the first insertion groove 120 a tothe first side portion 21 of the guide 20 and a third section (length:L3) from the second side portion 22 to the one surface 121 b of thesecond insertion groove 120 b.

A detecting device 3 a whose horizontally extending length is L2 may beinserted into the second section in the receiving unit 11. A detectingdevice whose horizontally extending length is L3 may be inserted intothe third section in the receiving unit 11. When the detecting device 3a whose horizontally extending length is L2 is inserted into the secondsection in the receiving unit 11, the guide 20 remains in a state beforethe detecting device 3 a is inserted, a part of a one-side surface ofthe detecting device 3 a is inserted into and fixed to the firstinsertion groove 120 a, the other-side surface is supported by aone-side surface of the detector support 23, and thus the detectingdevice 3 a may be fixed not to move. A part of the bottom of thedetecting device 3 a may be inserted into and fixed to the mountingportion 130 provided in the bottom fixer 13.

The connector 300 capable of charging the detecting device 3 a may beprovided in the receiving unit 11 of the receiving device 10.Specifically, the connector 300 may be provided at the bottom fixer 13.More specifically, the connector 300 may be provided at the mountingportion 130 on which the bottom of the detecting device 3 a is mounted.When the detecting device 3 a is accommodated in the receiving unit 11of the receiving device 10, the terminal 310 (see FIG. 10) provided inthe detecting device 3 a and the connector 300 provided in the receivingdevice 10 may come in contact with each other. By such a structure, thedetecting device 3 a may be charged while being accommodated in thereceiving unit 11 of the receiving device 10. Additional description ofthe connector 300 will be omitted because the description overlaps thatwith reference to FIGS. 2 to 4.

The detecting device whose horizontally extending length is L3 may beinserted into the third section in the receiving unit 11. In this case,the guide 20 remains in a state that is the same before and after thedetecting device is inserted, a one-side surface of the detecting deviceis supported by the detector support, and the other-side surface of thedetecting device may be inserted into and fixed to the second insertiongroove 120 b. A part of the bottom of the detecting device can beinserted into and fixed to the mounting portion 130 provided in thebottom fixer 13.

In this manner, even when the detecting devices have various sizes, thedetecting devices may be stably accommodated in the receiving unit 11according to the structure of the guide 20. Therefore, it is possible toprevent the detecting device from being moved when the main body 4 ismoved.

The body 51 may include a receiving unit 510 in which the detectorsupport 54 can be accommodated. The receiving unit 510 may be providedto correspond to a shape of the detector support 54. With respect to thereceiving unit 510, the body 51 positioned in one side of the detectorsupport 54 may be referred to as a first sidewall 51 a, and the body 51positioned in the other side may be referred to as a second sidewall 51b. A part of the body 51 facing one surface of the detector support 54may be referred to as a support surface 53.

An elastic member 56 may be positioned between the detector support 54and the support surface 53. The elastic member 56 may provide an elasticforce such that the other side of the detector support 54 is away fromthe support surface 53.

As an example, the elastic member 56 may be provided in the form of aspring whose two arms protrude from a circular spring portion. Any onearm may support one surface of the detector support 54, and the otherarm may support one surface of the detector support 54. The rotatingshaft 55 may be inserted into the circular spring portion connecting twoarms. A plurality of elastic members 56 may be provided. As an example,two elastic members 56 may be provided.

The rotating shaft 55may sequentially pass the rotating shaft insertion hole 52 b formed inthe second side portion 51 b of the body 51, the rotating shaftinsertion hole 540 formed in the detector support 54, and the rotatingshaft insertion hole 52 a formed in the first side portion 51 a.Therefore, the detector support 54 may be rotatably mounted in the body51.

When the elastic member 56 is mounted in the rotating shaft 55, therotating shaft 55 may sequentially pass the rotating shaft insertionhole 52 b formed in the second side portion 51 b of the body 51, therotating shaft insertion hole 540 formed in the detector support 54, aspring portion of the elastic member 56, and the rotating shaftinsertion hole 52 a formed in the first side portion 51 a.

As illustrated in FIG. 2 to FIG. 4, the guide 50 may be mounted in afront inner side surface of the receiving device 10 forming thereceiving unit 11. The guide 50 may be mounted in a rear inner sidesurface of the receiving device.

FIG. 13 is a side view of a guide when a guide according to anotherembodiment of the present invention is in a first position. FIG. 14 is aside view of a receiving device when a guide according to anotherembodiment of the present invention is in a first position.

As illustrated in FIGS. 13 and 14, when a detecting device 3′ isinserted into the receiving device 10′ in which the guide 50 accordingto another embodiment of the present invention is mounted, the otherside of the detector support 54 may be rotated to move forward(direction t5: refer to FIG. 13) by the detecting device 3′.

The detector support 54 may be rotated in the direction t5 andaccommodated in the receiving unit 510 positioned between the first sideportion 51 a and the second side portion 51 b. In this case, ahorizontally extending length of the detecting device 3′ may correspondto a length from one surface of a first insertion groove of the sidefixer 12 provided in the receiving device 10′ to one surface of a secondinsertion groove.

In this case, an arm supporting the detector support 54 between two armsof the elastic member 56 positioned between the detector support 54 andthe support surface 53 may move in a direction t6, and a distancebetween the two arms may decrease.

In the detecting device 3′, a part of a side surface of the detectingdevice 3′ may be slidably inserted into the first insertion groove andthe second insertion groove formed in the first side guide and thesecond side guide. The detector support 54 may slide along the firstinsertion groove and the second insertion groove, and may slidably pushthe detector support 54 when coming in contact with the detector support54. In the detector support 54, the other side of the detector support54 may be rotated in the direction t5 with respect to the rotating shaft55 due to a pushing force of the detecting device 3′ and accommodated inthe receiving unit 510 provided in the body 51.

In this manner, a part of a one-side surface of the detecting device 3′is inserted into the first insertion groove of the side fixer, a part ofthe other-side surface is inserted into the second insertion groove ofthe side fixer, and thus both sides may be fixed. Also, a bottom of thedetecting device 3′ may be mounted in and supported by the mountingportion 130 provided in the bottom fixer 13 that is positioned below areceiving unit 11′. Therefore, the detecting device 3′ may be stablyaccommodated in the receiving unit 11′ not to move even when the mainbody 4 is moved.

The connector 300 capable of charging the detecting device 3′ may beprovided in the receiving unit 11 of the receiving device 10.Specifically, the connector 300 may be provided at the bottom fixer 13.More specifically, the connector 300 may be provided at the mountingportion 130 on which the bottom of the detecting device 3′ is mounted.When the detecting device 3′ is accommodated in the receiving unit 11 ofthe receiving device 10, the terminal 310 provided in the detectingdevice 3′ and the connector 300 provided in the receiving device 10 maycome in contact with each other. By such a structure, the detectingdevice 3′ may be charged while being accommodated in the receiving unit11′ of the receiving device 10. Additional description of the connector300 will be omitted because the description overlaps that with referenceto FIGS. 2 to 4.

When the detector support 54 is inserted into the receiving unit 510 dueto an external force, the detecting device 3′ of a great horizontallyextending length may also be easily inserted into the receiving unit 11′without intervention of the detector support 54.

The receiving unit 11′ of the receiving device 10′ may be formed at aslant to have a predetermined angle. Description thereof will be omittedbecause the description overlaps that of the receiving unit 11 of thereceiving device 10.

Hereinafter, a case in which a detecting device of a short horizontallyextending length is inserted into the receiving unit 11′ will bedescribed.

FIG. 15 is a side view of a guide when the guide according to anotherembodiment of the present invention is in a second position. FIG. 16 isa side view of a receiving device when a guide according to anotherembodiment of the present invention is in a second position.

As illustrated in FIGS. 15 and 16, a detecting device 3 a′ according toanother embodiment of the present invention has a horizontally extendinglength that is any of a length from one surface of the first insertiongroove of the side fixer to the first side portion 51 a of the guide 50and a length from one surface of the second insertion groove to thesecond side portion 51 b of the guide 50. Hereinafter, the horizontallyextending length of the detecting device 3 a′ will be described as thelength from one surface of the first insertion groove of the side fixerto the first side portion 51 a of the guide 50.

When the detecting device 3 a′ illustrated in FIGS. 13 and 15 is removedfrom the receiving unit 11′, the detector support 54 may rotate in adirection t7 with respect to the rotating shaft 55 due to an elasticforce of the elastic member 56, and be removed from the receiving unit510 of the body 51. When the detector support 54 is rotated in thedirection t7, at least a part of the elastic force of the elastic member56 positioned between the detector support 54 and the support surface 53is used to rotate the detector support 54. When the detector support 54is rotated at a predetermined angle, the elastic member 56 may expandand have an elastic force smaller than that before the detector support54 is rotated. When the detector support 54 is rotated in the directiont7, an arm of the elastic member 56 supporting an inner side surface ofthe detector support 54 may move in a direction t8 while the inner sidesurface of the detector support 54 is supported. The direction t7 andthe direction t8 may be the same direction. Therefore, a distancebetween the arm supporting the inner side surface of the detectorsupport 54 and the arm supporting the support surface 53 of the body 51may increase.

As an example, when the detecting device 3 a′ whose horizontallyextending length is L1 is removed from the receiving unit 11′, a firstsection (length: L1) from one surface of the first insertion groove ofthe side fixer to one surface of the second insertion groove may bepartitioned by the detector support 54 into a second section (length:L2) from the one surface of the first insertion groove to the first sideportion 51 a of the guide 50 and a third section (length: L3) from thesecond side portion 51 b to the one surface of the second insertiongroove.

The detecting device 3 a′ whose horizontally extending length is L2 maybe inserted into the second section in the receiving unit 11′ and thedetecting device whose horizontally extending length is L3 may beinserted into the third section in the receiving unit 11′. When thedetecting device 3 a′ whose horizontally extending length is L2 isinserted into the second section in the receiving unit 11′, the guide 50remains in a state before the detecting device 3 a′ is inserted, a partof a one-side surface of the detecting device 3 a′ is inserted into andfixed to the first insertion groove, the other-side surface is supportedby a one-side surface of the detector support 54, and thus the detectingdevice 3 a′ may be fixed not to move. A part of a bottom of thedetecting device 3 a′ may be inserted into and fixed to a mountingportion provided in a bottom fixer 13′.

A detecting device whose horizontally extending length is L3 may beinserted into the third section in the receiving unit 11′. In this case,the guide 50 remains in a state that is the same before and after thedetecting device is inserted, a one-side surface of the detecting deviceis supported by the detector support, and the other-side surface of thedetecting device may be inserted into and fixed to the second insertiongroove. A part of the bottom of the detecting device may be insertedinto and fixed to the mounting portion provided in the bottom fixer 13′.

In this manner, when the detecting devices have various sizes, thedetecting devices can be stably accommodated by the receiving unit 11′according to the structure of the guide 50. Therefore, it is possible toprevent the detecting device from being moved when the main body 4 ismoved.

The receiving unit 11′ of the receiving device 10′ may be formed at aslant to have a predetermined angle. Description thereof will be omittedbecause the description overlaps that of the receiving unit 11 of thereceiving device 10.

FIG. 17 is a diagram illustrating a part of a receiving device accordingto still another embodiment of the present invention.

As illustrated in FIG. 17, a guide 70 provided in the receiving deviceaccording to still another embodiment of the present invention ismovable along a rail 74. The rail 74 may be provided on an inner sidesurface 72 c of the receiving device forming the receiving unit. Therail 74 may extend in a horizontal direction. Side portions 72 a and 72b are provided at both ends of the inner side surface 72 c,respectively. Side fixers 71 a and 71 b having an insertion hole intowhich a part of a side surface of the detecting device is slidablyinserted may be provided in the side portions 72 a and 72 b. A directionin which the insertion hole extends may be perpendicular to a directionin which the rail 74 extends. A bottom fixer 73 configured to support abottom of the detecting device may be provided in the lower part of thereceiving device.

Since the guide 70 is horizontally movable along the rail, in order tofix both sides such that the detecting device is stably accommodated inthe receiving unit, a position of the guide 70 may be moved according toa size of the detecting device.

As an example, in the guide 70, the guide 70 may be moved along the rail74 in order to insert a detecting device having a horizontally extendinglength of w2 that is greater than w1 between the second side fixer 71 band the guide 70 when a distance from the second side fixer 71 b is w1.The guide 70 may move to a point at which a length from the second sidefixer 71 b is w2. Therefore, the detecting device may be insertedbetween the second side fixer 71 b and the guide 70, and the detectingdevice may be fixed not to move by side surfaces of the second sidefixer 71 b and the guide 70.

Meanwhile, the guide 70, which is movable along the rail 74, has aposition that may be fixed by various types of stopper structures. Sincethe stopper structure of the related art can be used, a detaileddescription thereof will be omitted

FIG. 18 is a diagram illustrating a part of a receiving device accordingto still another embodiment of the present invention.

The plurality of guides 80 are movable along a rail 84 thatextends in a horizontal direction. The rail 84 may be provided on aninner side surface 82 c of the receiving device forming the receivingunit. Side portions 82 a and 82 b are provided at both ends of the innerside surface 82 c, respectively. Side fixers 81 a and 81 b having aninsertion hole into which a part of a side surface of the detectingdevice is slidably inserted may be provided in the side portions 82 aand 82 b. A direction in which the insertion hole extends may beperpendicular to a direction in which the rail 84 extends. A bottomfixer 83 configured to support a bottom of the detecting device may beprovided in the lower part of the receiving device.

According to the user's convenience, a guide adjacent to any of amongthe plurality of guides may be separated at an interval to correspond tothe horizontally extending length of the detecting device and then thedetecting device may be inserted into the guides.

For example, the guide 80 may include a first guide 80 a and a secondguide 80 b. In order to accommodate a detecting device whosehorizontally extending length is w3 in the receiving device, the usermoves the first guide 80 a or the second guide 80 b along the rail 84,and when an interval between the first guide 80 a and the second guide80 b is w3, fixes positions of the first guide 80 a and the second guide80 b and may insert the detecting device therebetween. The detectingdevice may be fixed not to move even when the main body 4 is moved by aside surface of the first guide 80 a and a side surface of the secondguide 80 b.

When positions of the first guide 80 a and the second guide 80 b areappropriately regulated, the detecting device may be inserted intospaces between the first side fixer 81 a and the first guide 80 a,between the first guide 80 a and the second guide 80 b, and between thesecond guide 80 b and the second side fixer 81 b. Therefore, theplurality of detecting devices may be accommodated in one receivingdevice.

The number of guides that are movable along the rail 84 is not limitedto the above. Meanwhile, since the stopper structure of fixing positionsof the first guide 80 a and the second guide 80 b in the related art canbe used, a detailed description thereof will be omitted.

According to the above structure, detecting devices of various sizes maybe stably accommodated in the receiving device having one receivingunit.

While the receiving device provided in the mobile X-ray imagingapparatus has been described above, the structure in which the guide isprovided in the receiving device of the present invention is a structurein which a plate-shaped object of a different size may be stablyaccommodated in one receiving unit. Therefore, the structure may beutilized as a space for receiving a detector for X-ray imaging andutilized in other fields.

According to the embodiment of the present invention, the detector maybe stably supported even when a detector having a smaller size than thereceiving unit is accommodated in the receiving unit by a detectorfixing device provided in the receiving device.
